To remove a tado° device from your Home, follow these steps:
Go to Settings > Rooms & Devices in your tado° app.
Choose the device you wish to delete from the list.
Select the three dots in the top right corner of the screen and choose “Remove device from home”.
Removing the Bridge X or Heat Pump Optimizer may cause your tado° devices to go offline if it is your only Thread border router. If you have several Thread border routers, your tado° devices will stay online, but your network range may be affected.
